[cfe-dev] patch for generalizing stdint for n-bit bytes

[Ray Fix]

Hello ClangWorld,

This is a resend since my original message was too large and got  
filtered from the list.  Sorry about that;

The linked patch is the work of Ken Dyck which I merget to work with  
the top of the tree (R84372).   This patch generalizes some of the  
defines produced by the preprocessor in preparation for future patches  
to support of n-bit bytes.

Some other highlights include the addition of 40 new test cases that  
help better validate the preprocessor and target defines.  It also  
gets rid of std::vector<char> in favor of llvm::raw_ostream to create  
defines.

My hope is that someone with commit authority can look these changes  
and shepherd them in or provide feedback for any additional mods/work  
that is required for them to be accepted.
